Quick answer
A bikini brief should sit at or just below your hip bones with the waistband flat and comfortable, offering moderate back coverage without pulling. In the Extra-Ordinary Bikini Brief, start with your usual size and adjust based on how the folded edge sits on your hips.
Why the folded edge changes how you judge fit
The Extra-Ordinary Bikini Brief uses a smooth folded edge instead of elastic. That means there is no elastic band to dig in, but it also means the fit relies on the fabric and cut rather than stretch. When you try it on, check that the folded edge lies flat against your skin without rolling or gaping. If it rolls, the brief may be too small; if it gaps, it may be too large.
What moderate coverage means in practice
Moderate back coverage sits between a full brief and a thong. In the Extra-Ordinary Bikini Brief, the back coverage is designed to cover the upper part of the bottom without riding up. To test coverage, bend, sit and walk in front of a mirror. The fabric should stay in place without needing adjustment. If it rides up, the size or rise may not suit your shape.
When to size up or down
Because the fabric is soft and slinky, it moves with you rather than compressing. If you are between sizes, consider your preferred fit: choose the smaller size for a closer fit or the larger size for more relaxed coverage. Always check the size guide and remember that the folded edge should not leave deep marks after a few minutes of wear.
How to check the rise, coverage and size of your bikini brief
- Try it on over your usual underwear: Put the brief on over a thin pair of your own underwear to see how the rise sits without committing to a full try-on. The waistband should rest at or just below your hip bones, not up at your natural waist or down on your thighs. If the waistband sits above your hip bones, the rise is higher than a classic bikini; if it sits below, it may be too low for your preference.
- Check the folded edge: Run a finger under the folded edge around the legs and waist. It should lie flat and smooth against your skin without rolling, twisting or gaping. A rolled edge usually means the brief is too small; a gaping edge means it is too large. The folded edge replaces elastic, so a flat, comfortable lie is your main fit signal.
- Assess back coverage: Stand in front of a mirror and bend forward, then sit down. The back should cover the upper part of your bottom without riding up or creating a visible line. Moderate coverage should stay in place through these movements. If the fabric rides up when you move, try a larger size or a different style with more coverage.
- Decide on size: Use the size guide as a starting point. If you are between sizes, choose the smaller size for a closer fit or the larger size for more relaxed coverage. The brief should feel snug but not tight, and the folded edge should not leave deep marks after a few minutes. Your usual size is the best starting point; adjust only if the folded edge or coverage tells you otherwise.
